Answer:

7 7/4 t - 1

Step-by-step explanation:

The perimeter of the quadrilateral is the sum of all the sides combined together

Given the length of the sides as (2 1/4t−5), (4t+3), (1/2t−1), and (3t+2),

Taking the sum;

Perimeter = (2 1/4t−5)+(4t+3)+(1/2t−1)+(3t+2)

Perimeter = 9/4 t - 5 + 4t + 3 + 1/2 t - 1 + 3t + 2

Collect like terms;

Perimeter = 9/4 t + 1/2 t + 4t + 3t -5 + 3-1 + 2

Perimeter = (9t-2t)/4 + 7t -1

Perimeter = 7/4 t + 7t - 1

Perimeter = 7 7/4 t - 1

Answer:

x = 17

Step-by-step explanation:

The sum of all angle measures in any triangle is 180 degrees.

  • Thus, 23 + 5x - 18 + 90 = 180.

Step 1: Simplify both sides of the equation.

  • (5x)+(23+90-18)=180
  • 5x+95=180

Step 2: Subtract 95 from both sides.

  • 5x+95-95=180-95
  • 5x=85

Step 3: Divide both sides by 5.

  • 5x/5=85/5
  • x=17

Step 4: Check if solution is correct.

  • (5*17-18)+23+90=180
  • 67+23+90=180
  • 180=180

Thus, x = 17.
